A sexual act almost equivalent to the oral sex act "the blowjob", except for the fact that the person performing the fellatio make a sucking noise, such as a vacuum cleaner would make. Sounds include: "Shhlck", "Slllllluuuuuuupp" , etc.

When some little bitchboy is acting like a little tiny pee pee poo poo baby and messing up the group plans.
